Solution

1. Tire Inspection and Adjustment

Sub-steps:
1. Check tire pressure using a tire pressure gauge and inflate as needed.
2. Inspect tread depth with a tread depth gauge, replacing tires if they are worn unevenly.
3. Rotate tires if necessary to ensure even wear.

2. Wheel Balancing

Sub-steps:
1. Remove the affected wheel from the vehicle using a socket set.
2. Mount the wheel on a wheel balancer.
3. Add weights as needed to balance the wheel properly.
4. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

3. Suspension and Drivetrain Inspection

Sub-steps:
1. Raise the vehicle on a jack and secure it with jack stands.
2. Visually inspect suspension components such as control arms, bushings, and struts for wear or damage.
3. Check the driveshaft for any signs of bending or excessive play.
4. If any components are damaged, replace them with OEM or high-quality aftermarket parts.

4. Wheel Alignment

Sub-steps:
1. Use a wheel alignment machine to measure the alignment angles.
2. Adjust camber, caster, and toe settings according to manufacturer specifications.
3. Test drive the vehicle to ensure that steering alignment is correct.
